Tokonomics is an AI cost metering proxy that sits between your app and any LLM provider. Every API call is tracked, every token counted, and you get alerts before costs spiral. One URL change, no SDK, works with any language.

Supports OpenAI, Anthropic, DeepSeek, Gemini, Mistral, Groq, xAI, and any OpenAI-compatible API. Features include real-time cost tracking with 8-decimal USD precision, budget alerts via email, Slack, and Teams, hard spending caps that block requests at the API level, tag-based cost attribution by team, feature, or customer, and a full analytics dashboard.

Free plan includes 100 API calls per month. Pro plan at $49/mo gives unlimited calls, unlimited alerts, hard caps, and 90-day data retention.
